NUT-LOCKING DEVICE.

Specification of Letters Patent.

Application filed October 2, 1911.

Patented J one 3, 1913. Serial No. 652,285.

lie it known that I, SAMUEL WV. (laureatrnn, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvcments in Nut-Locking Devices, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to nut locking devices especially designed tor rail joints or structures having a plurality of bolts and nuts that are arranged in a row.

The primary object of my invention is to provide simple and effective means for preventing nuts from becoming atmidentally displaced relatively to bolts due to the vi brations of the structures in which the bolts are mounted.

l attain the above objects by a mechanical construction that will be hereinafter specitically described and then claimed. and retmience will now be had to the drawiiur, wherein like numerals denote corresponding parts throughout the several views, in which l igurc l is a side elevation of a rail joint provided with the nut locking members, Fig. :5 is a cross sectional view taken on the line li it of Fig. 1, Fig. 3 is a similar view ta hen on the line III III of 1, Fig. 4 is a perspective view of the combined coupling plate and washer forming a part the nut locking device, and Fig. is a perspective view of one of the nut locking members.

.l.'he reference numeral It denotes rails having the confronting ends thereof braced by splice bars 2 and 3 and these bars are held in engagement with the rails t by a pluralit y of bolts 4t extending through openings 53 and 6 provided therefor in the bars and rail. The threaded ends of the bolts 4t protrude :l'rom the outer side of the splice bar and are adapted to receive nuts 7. Prior to mounting the nuts upon the bolts 4t, an ob wag base plate 8 is placed upon said bolts,

s, id plate having openings 9 to provide clearance for the threaded ends of the bolts.

50 (The base plate 8, intermediate the ends there ct, is stanmed or pressed to provide a strap or housing 1.0 that extends outwardly from the outer side of the base plate 8. The strap or housing 10 has open ends in a line with the openings t) of the plate 8. After the plate 8 has been placed upon the bolts against the splice bar 3, the nuts 7 are screwed upon the bolts and tightened against the plates 8. It is then that oblong locking members 12 are placed upon the nuts 7, said members having openings 13 to receive the nuts 7 and surrounding said openings are casings lit that inclose the facets of the nuts 7, thus preventing said nuts from rotating. 'lhe cmrlront-ing ends of the members 12 are provided with malleabletongues 15 and these tongues are placed in the strap or housing 10 said tongues overlapping as best shown in Figs. 1 and 3 and said tongues in connection with said housing 10 connect the locking members to the plate 8 so as to prevent the locking members from becoming accidentally displaced by providing two locking members, it' one of the bolts at one side oi. the joint should become damaged it only necessitates the removal 01 one of the locking members. It is preferable to punch and stamp the members 12 to provide the casings ll and these casings can be hexagon or rcctmigular in cross section to accommodate hexagon or rectangular nuts.

ith the bolts 4 held from rotation in the splice bar 2 in the ordinary and well known manner, it is impossible for the bolts to rotate and as the nuts are prevented from rotating by the casings 141, it is obvious that the rail joint will remain intact even though subjected to vibrations.

While in the drawing there, is illustrated a pre'l'erred embodiment of my invention, it is to be understood that the structural elements thereof are susceptible to such changes as fall within the scope of the appended claims.

What T claim is Means for locking a plurality of nuts disposed in the same plane, comprising a base plate provided with bolt openings and having an open ended keeper located mid-way the ends of the plate and projecting from the outer face of the latter, combined With In testimony whereof I affix my signature a pair (if nut-securing plates disposed in the in the presence of two witnesses.
